CHALK LOADING DEVICE Filed Sept. 20, 1948 //v vE/vm/e MARTIN A. GUMBEL.

Patented June 2Q, 1950 Application September 20, 1948, Serial No. 50,177

1 Claim. 1

The present invention relates to improvements in a chalk loading device wherein a suitable frame or body, having a hopper arranged to contain a supply of tailors chalk wafers or slabs, and a pair of spaced, parallel grooves arranged to transversely intersect the bottom of said hopper, operates in conjunction with a recess in said grooves to aline a slotted chalk holder therewith, and a plunger slidably mounted within said grooves and arranged to move a wafer from said hopper into a protective slot within said chalk holder.

The primary object of the present invention is to provide a new and improved chalk loading device having improved means arranged to load or insert an extremely thin and fragile wafer of tailors chalk into a protective holder, whereby a thinner marker may be provided to produce thinner lines upon a fabric or garment during a tailoring process.

Another object of the present invention is to provide a new and improved device of the character set forth having a greatly simplified and economically produced construction and operation and a maximum efliciency.

The improvement comprises the details of construction and the arrangement of the several parts as disclosed in the drawings forming a part of the present application, and in which Fig. 1 is a vertical sectional view of my improved device taken on line II of Fig. 2, in the direction indicated;

Fig. 2 is a top plan view, partly in section, and with the chalk holder shown in position in dotted lines;

Fig. 3 is a front elevation;

Fig. 4 is an enlarged, broken view, partly in section, of the device in operative position;

Fig. 5 is a plan view of the chalk holder.

Referring to the drawings:

The numeral l is used to designate a suitable frame or integral body having a vertically disposed hopper 2 formed thereon with the front and bottom thereof substantially open, and with ledges or shoulders 3 formed upon opposite sides of said hopper at the bottom thereof. A pair of horizontally disposed spaced and parallel grooves 4 within said body I are arrange to intersect the bottom of said hopper 2 and substantially alined with the shoulders or ledges 3 thereof, said grooves 4 being extended on opposite sides, or in front and back, of said hopper 2, as clearly disclosed in Fig. 1 of the drawings. The front portions of said grooves 4 are enlarged or expanded to form recesses 6 arranged to receive and hold in alinement with said grooves 4 the slot 1 of a chalk holder 8, one of said recesses being provided with preferably pointed lug or gage 9 arranged to engage a similar notch II in one edge of said chalk holder 8, whereby said holder 8 more effectively and accurately may be held in proper alinement with said hopper, as indicated in dotted lines in Fig. 2 of the drawings.

Slidably mounted within the grooves 4 upon the opposite or back of the body I, is a, suitable plunger [2 having a sharp lip upon the front edge thereof, as at l4, said lip l4 being arranged to select or separate the bottom or lowermost wafer of a pile of extremely thin wafers of soapstone, or tailors chalk, piled within said hopper 2, as disclosed in Fig. 4 of the drawings, from the remainder of said wafer I 6 in said hopper.

In operation; a plurality or supply of extremely thin wafers or sticks l6 of a suitable marking chalk is piled Within the hopper 2, such insertion being facilitated by the substantially open front and bottom of said hopper, to permit the insertion of a finger and thumlo, not shown, of an operator in placing said pile of sticks or chalk within said hopper, said pile of wafers or sticks or slabs It being settled or placed upon the opposite shoulders 3 within the said hopper 2 and with the lowermost wafer l6 alined with the grooves 4. The slotted holder 8 being in position with its groove or slot 1 substantially alined with the bottom stick 16, the plunger I2 is moved inwardly which will cause the sharp lip l4 thereof to be inserted between the two lowermost sticks or wafers [6, so that the said plunger l2 will engage and move the lowermost wafer I'G directly into the slot 1 of said holder 8, it being understood that sufficient friction is provided within or between said slot surfaces and wafer to efiectively hold the latter in position within said marker.

A second plunger 20 is slidably mounted within the holder 8 and arranged to extrude the wafer l6 gradually therefrom as the thin exposed edge thereof becomes worn and a new edge is required.

By means of this improved chalk loading device, a much thinner and therefore more economical and efiicient chalk marker is provided whereby an extremely thin yet distinct mark or markings may be had, and a saving of time and labor in shaping a thin edge upon the present thicker sticks of chalk may be eliminated, as well as a considerable saving of chalk.

Having thus described my invention, I claim- The combination with a, slotted chalk holder 3 of a body having a vertically disposed hopper, substantially open at the front and bottom thereof and having ledges on opposite sides of said open bottom, transverse parallel grooves intersecting the bottom of said hopper and substantially alined with said shoulders or ledges, and extended beyond opposite sides of said bottom of said hopper, said grooves beyond one side of said hopper having an enlarged recess arranged to engage and hold said slotted chalk holder alined with said grooves and with a wafer in said hopper resting upon said ledges; and a plunger slidably mounted within the opposite ends of 4 said grooves and having a sharp lip arranged to separate the lowermost of a pile of wafers within said hopper, and to move said water into said slotted chalk holder.
